@jon These are two separate questions, one people who do some business and ones who's sole income is salary, but I think *no* country requires tax returns for the second type. I don't even know how is it possible to make all people, including the uneducated, the illiterate etc. fill out such a form, if they try to do the same thing here it's just not going to happen.
And people who have some small business or work freelance it's really impressive if they have the info prefilled and easy to fill.
@jon if you're not self-employed, you get the pre-filled tax return and you need just to confirm, or you can rectify if needed - this in Sweden 🇸🇪
(of course if you're self-employed this doesn't apply)
@jon In Germany you can opt in to have your employer submitting all relevant data to the tax office and have your tax form prefilled with the data. Not sure though how many people are using it
I've been using it for several years now. I was singing the praises of digitalization when they introduced the system
@jon here in Portugal under some basic conditions it's all automatic and click next. I could do it for the first time last year like that. The previous years I was not under the right conditions for that option. When it has to be manually there's a few places to edit and some prefilled values in some places.
Anyway I guess most people just go and pay to an outsider person to fill the taxes, it's usually much simpler since it's all very confusing.
